Both Ubuntu and Debian provide Python modules in their apt repositories, but it doesn't host the less popular modules. The version of the available Python modules is also tied to the version of Ubuntu or Debian.

You need to install Python modules from Python Package Index (PyPI) if you require the latest Python modules or those not hosted in apt repositories. pip allows installing Python packages hosted in PyPI, but it's not installed by default in Ubuntu or Debian. You can install pip on Ubuntu or Debian using apt at the terminal.

Steps to install pip on Ubuntu and Debian:

  1. Launch terminal.
  2. Update apt's package list.
    $ sudo apt update
    [sudo] password for user: 
    Hit:1 http://ports.ubuntu.com/ubuntu-ports impish InRelease
    Hit:2 http://ports.ubuntu.com/ubuntu-ports impish-updates InRelease
    Hit:3 http://ports.ubuntu.com/ubuntu-ports impish-backports InRelease
    Hit:4 http://ports.ubuntu.com/ubuntu-ports impish-security InRelease
